How to get all of the BLE connection state?

[Jordan Archer]

Aside from the connection interval, I'd like to know if the 2Mhz phy is enable along with Data Packet Length Extension and Connection Event Length Extension.

Is there a way for the app to get this information?

When the PHY is updated you will get a event, BLE_GAP_EVT_PHY_UPDATE, with the PHY that is used. See this and this link.

This is handled by the GATT Module. You can read it with the function nrf_ble_gatt_data_length_get().

This is something that is either enabled or disabled. When enabled the SoftDevice will dynamically extend the connection event when possible.

If sd_ble_opt_set(BLE_COMMON_OPT_CONN_EVT_EXT, &opt) returned NRF_SUCCESS, it's enabled. You cannot use sd_ble_opt_get for this option. See this link. Snippet on how to enable:

    ret_code_t err_code;
    ble_opt_t  opt;

    memset(&opt, 0x00, sizeof(opt));
    opt.common_opt.conn_evt_ext.enable = 1;

    err_code = sd_ble_opt_set(BLE_COMMON_OPT_CONN_EVT_EXT, &opt);
    APP_ERROR_CHECK(err_code);
